Abstract: The structure of the title compound, (C16H17N2)3[Co(CN)6]·5H2O, consists of three 3,4,7,8-tetramethyl-1,10-phenanthrolin-1-ium cations, a [Co(CN)6]3- anion and five water molecules of crystallization, one of which is disordered over two sets of sites in a 0.587 (15):0.413 (15) ratio. The [Co(CN)6]3- anion exhibits an octahedral geometry. In the structure, cations and anions are linked alternatively through O-H...O, O-H...N, N-H...O and N-H...N hydrogen bonds, [pi]-[pi] interactions [centroid-centroid distances = 3.523 (2)-4.099 (2) Å] and van der Waals forces, forming a three-dimensional supramolecular network.
